To draw the complete structure of cholesterol (C27H46O) showing all carbon and hydrogen atoms, we need to follow the given shorthand structure and add the missing hydrogen atoms. The complete structure of cholesterol is as follows: ``` H2C—CH2 / \ H2C CH2 / \ H2C CH2 / \ H2C CH2 / \ H2C CH / \ CH2—CH2—CH2—CH2—CH2—CH2—CH \ O H ``` In this structure: - Each point where the lines meet represents a carbon (C) atom. - The carbon atoms are connected by single bonds, forming a tetrahedral structure. - The hydrogen (H) atoms are attached to the carbon atoms, with four bonds to each carbon atom. - The oxygen (O) atom is attached to the last carbon atom, forming a hydroxyl group (-OH). This complete structure of cholesterol shows all the carbon and hydrogen atoms, as per the given shorthand representation.
